Description

Technical Field

[0001] The utility model relates to the technical field of battery detection, in particular to a double-station soft-pack battery thickness measuring device. Background Art

[0002] In the prior art, a soft-pack battery refers to a battery formed by wrapping an electric core with an aluminum-plastic film. Different from traditional steel-shell batteries, the outer shell of a soft-pack battery is an aluminum-plastic film with a soft structure. After production, there will be differences in the thickness of different soft-pack batteries in the same batch. Therefore, the qualified acceptance standard for soft-pack batteries usually sets a certain thickness range, and soft-pack batteries within this thickness range can be determined to be qualified. When measuring the thickness of existing soft-pack batteries, there are the following problems: Since the two surfaces of a soft-pack battery are not completely flat, the thickness at different positions of the same soft-pack battery may vary. Especially as people pursue higher energy density of soft-pack batteries, making soft-pack batteries thinner and larger in area at the same time, the situation of inconsistent thickness at different positions of soft-pack batteries becomes more obvious. Currently, the main thickness measurement method is to take the average value by measuring multiple points, that is, to measure the thickness at several fixed points on the soft-pack battery and then take the average value of each measurement value. This thickness measurement method has the following deficiencies: First, the same soft-pack battery needs to be measured multiple times, and the measurement process is cumbersome, resulting in too low measurement efficiency; Second, the principle of taking the average value is that the more times the measurement is taken, the closer the obtained average value is to the true thickness value. However, considering the actual situation, the number of measurements of the same battery on the battery production line will not be too many, so there is a difference between the obtained thickness value and the actual thickness value of the soft-pack battery.

[0003] The Chinese utility model patent with the application number 201921786978.X discloses a soft-pack battery thickness measuring machine, which includes a thickness measuring mechanism. The thickness measuring mechanism includes a detection platform. A moving groove for accommodating a soft-pack battery carrier is provided in the middle of the detection platform. Support columns are respectively connected to both sides of the detection platform, and a load-bearing plate is connected to the upper ends of the support columns. A plurality of pressing plates are provided below the load-bearing plate. A lifting device is connected to the middle of the load-bearing plate. The lifting rod of the lifting device passes through the load-bearing plate and is connected to the pressing plate. A plurality of pressure rods are connected below the pressing plate, and pressure sensors are installed on the pressure rods; The load-bearing plate is connected with a displacement sensor for sensing the moving distance of the pressing plate. However, this kind of soft-pack battery thickness measuring machine has a relatively complex structure, many components, a relatively cumbersome detection method, and its detection structure is in direct contact with the soft-pack battery, resulting in easy rigid collision and damage between the soft-pack battery and the detection structure.

[0031] Working principle:

[0032] When measuring the thickness of the soft-pack battery, start the device. The output end of the thickness measuring cylinder 10 extends. Under the action of the pulley group, the thickness measuring base 12 drives the thickness measuring press block 13 to descend and fit with the upper surface of the workbench 7. The thickness measuring sensor 14 records the distance between it and the ground at this time and sets it as the initial value. Then the output end of the thickness measuring cylinder 10 retracts, and the thickness measuring base 12 drives the thickness measuring press block 13 to rise. Place two groups of soft-pack batteries side by side and at intervals on the workbench 7. The output end of the thickness measuring cylinder 10 extends, and the thickness measuring base 12 drives the thickness measuring press block 13 to descend and fit and press against the upper ends of the soft-pack batteries. The thickness measuring sensor 14 detects the distance between it and the ground at this time. Subtracting the initial value from this distance data can obtain the thickness of the soft-pack battery. After detecting a group of soft-pack batteries, the output end of the moving cylinder 5 expands and contracts to drive the workbench 7 to move horizontally, so that the workbench 7 moves to another station to measure the thickness of another group of soft-pack batteries.
